What Researchers Did
Researchers conducted a systematic review of studies published between 2004 and 2012 to summarize the work performed on hyperbaric oxygen therapy and cancer.
What They Found
Based on this and two previous reviews, there is no evidence that hyperbaric oxygen therapy stimulates tumour growth or enhances recurrence, and its use in patients with malignancies is considered safe. Conversely, some evidence suggests that hyperbaric oxygen therapy might have tumour-inhibitory effects in certain cancer subtypes.
Canadian Relevance
This systematic review did not include any specific Canadian data or studies.
Study Limitations
The review highlights the need for expanded knowledge on the effects and mechanisms of tumour oxygenation, indicating current understanding is incomplete.
